URINAL.

Applicationfiled March 30, 1898. Serial No. 675,670. (No modeld fo @ZZ lull/(mt t 71u03/ coloc-ern:

` Beit known that I, WILLIAM H. LLOYD, of Brookline, in the county of Norfolk and State of Massachusetts, have vinvented certain new and useful Improvements in Urinals, of which the following is a specification.

This invention has for its object to provide a urinal embodying a receivingbowl, an outlet therefor adapted for attachmentto a discharge-pipe, a trap adapted to hold abody of water in position to seal the outlet, and means for changing the water in the said trap, so that urine will not stand therein long enough to create a nuisance. y

The invention consists in the novel features of construction and relative arrangement of parts hereinafter fully described in the specification, clearly illustrated in the drawings, and particularly pointed out in the claim.

Cf the accompanying drawings, forming a part of this specification', Figure l represents a front elevation of a urinal embodying my invention. Fig. 2 represents a section on line 2 2 of Fig. l. Fig. 3 represents a section on line 3 3 of Fig. 2.

The same letters and numerals of reference indicate the same parts in all the iigures.

Myimproved urinal comprises abowl having an enlarged front opening, the lower edge 2 of which is raised above the bottom 3 of the bowl. The back wall 4 of the bowl extends below the lower edge 2 of the front opening. An outlet-passage 5 extends upwardly from the bottom of the bowl behind the back wall 4 and above the lower end 9 thereof and communicates with a downwardly-extending passage 6, which terminates in a horizontal neck 7. Said neck projects from the back of the bowl far enough to be connected with a discharge-pipe Z). The bowl, back, and outletpassage 5 form a trap adapted to retain a body of waterin position to seal the outlet-passage, as shown in Fig. 2. The passages 5 (i are arranged to form a siphon, of which the passage 6 is the longer leg, the saine extending below the lowest portion of the passage 5, so that the siphon will act to draw water from the bowl until ythe water-line is below the point i).

Behind the back wall et is a water-receiving chamber 8, the upper end of which communicates with the supply-pipe c, which delivers waterrto the bowl, the arrangement shownin the drawings being such that a part of the water delivered by the pipe c enters the tubular rim d of the bowl and flows down the inner sides of the bowl, while a part enters the chamber S. The upper portion of the saidchamber is'enlarged, as shown in Fig. 3, so that it is adapted to hold a considerable quantity of water. From the lower portion of the chamber 8 extends aV contracted outlet e, which discharges a small stream into the lower portion of the bowl, preferably at the junction of the outlet-passage 5 with the bowl.

Beside the upper portion of the chamber 8 is a retarding-chamber 80, which communicates with the chamber S through orifices 19 and 2O in a partition 18 between the two chambers. The retarding-chamber is adapted to contain enough water to fill the trap, or substantially so, and said chamber is filled wit-h wat-er from the chamber 8 during the flushing discharge. The said discharge is usually sufficient to more than fill the chamber 8, the water accumulating therein faster than itescapes through the contracted outlet e, so that the chamber SO is illed before the water can subside from the chamber 8.

It will be seen that the chamber 8 is extended vertically to a considerable height above the trap, and therefore holds a column of water, which is discharged into the trap with suflicient force to cause an effective. removal of the contents of the trap, an outward iiow through the passage 5 being induced by the jet discharged from the chamber 8. After the iiow from the chamber 8 has ceased the retarding-chamber SO continues to discharge water into the trap, the capacity of lthe reaction of the siphon to displace the water left in the trap, and thus insure the complete removal of the urine therein', the trap being filled by the pure water discharged from the chamber SO. The bowl is thus kept clean, and deposits on its surface from the urine are prevented.

The location of the contracted outlet e so as to discharge directly into the bottom of IOO the trap and in a direction toward the uptake 5 of the siphon is a material factor in this keeping of the bowl clean, for it insures that nothing whatever uncleanly shall be left at the bottom of the bowl either during the flushing operation or afterward while the chamber 80 is being emptied.

I do not limit myself to the form and arrangement of the retarding-chamber here shown, and the same may be variously modied without departing from the spirit of my invention.

To enable obstructions to be removed from the outlet e, I provide a clean-out nipple 7L, having an orifice h extending to the outlet e. Said orifice is closed by a removable screw.

It will be seen that the water-receiving chamber S extends above the trap in a substantially vertical plane from the point of discharge from said chamber to the bowl and that the passage for the water through the chamber 8 to the contracted oullet communicating with the bottom of the trap is a substantially straight one, and hence offers the least resistance to the passage of water therethrough and also occupies the minimum amount of space at the rear of the bowl of the urinal. It will also be seen that the retarding-chamber 8O is located at one side of the I chamber 8 and in the same plane therewith, thus providing a reservoir for water, so as to ill the trap, as heretofore describedrwithout requiring the setting of the bowl forward in order to accommodate the retarding-chamber at the rear. In other words, the receivingchamber and the retarding-chamber are in one plane or side by side at the rear of the bowl.

I claimy A urinal having a trap at its lower port-ion, a water-receiving chamber 8 extending from the upper to the lower portion of the bowl and arranged to receive water at its upper end from a supply-pipe connected with the bowl, its lower end discharging into the bottom of the trap, and a retarding-chamber 80 located above the trap and communicating with the chamber 8, and having a capacity substantially equal to that of the Trap, the said receiving-chamber 8 and retarding-chamber 80 being located in one plane or side by side at the rear of the bowl.

In testimony whereof I aiix my signature in presence of two witnesses.
